An airbag assembly, comprising:
- an inflator to supply inflation gas;
- and
- an airbag cushion configured to expand and deploy toward a seating position of a vehicle, the airbag cushion comprising:
- a main chamber;
- a secondary chamber coupled to the main chamber, wherein the secondary chamber is separated from the main chamber by a panel including two vents to allow the inflation gas to pass from the main chamber into the secondary chamber;
- and
